To all whom it may concern: v

Be it known that I, RAY G. CoA'rns, a

citizen of the United States, residing in which in substantiallyall'cases were unitary structures with openings running therethrough.Unitary structure tiles usually represent a larger integral mass of tilewhich is liable to crack or break when in use and also which does notlend itself easily to heating up due to the relatively large mass anddue to the fact that the interior cavities are usually heated at adifferent rate from the exterior of the tile.

The present invention overcomes the difficulties of the known art byproviding a runner tile formed in sections in such manner thateachsection carries a part of the runner tile opening and'thatthe sectionsthemselves, relatively speaking, are flat tilelike members. Furthermore,the opening through the tile is preferably formed in such'manner thatwhen the sections of the tile are assembled the completed opening isoval in cross section so that the gate may be easily broken after theingot is frozen. Preferably also the tile is wedge-shaped and isarranged to set in the mold body in such manner as to lift out when theingot is stripped from the mold. This facilitates re-use of the runnertile, because the sections of the tile fall away from the gate withoutthe necessity of 'breaking the tile to remove it from the ingot.

, In view ofthe foregoing-it may be stated that the principal object ofthe invention is to provide a runner tile for metallurgical use whichtile is formed in two sections in such manner as to easily be strippedfrom themetal forming the root in the runner tile when the metalsolidifies.

A still further object of the present invention is a runner tileprovided with an oval runner conduit whereby the necessary crosssectional area of the'runner conduit may be obtained in a tilewhich isrelatively thin and narrow.

A still further and more specific objectof the present invention is arunner tile of the character specified wherein sand grooves are providedon the sides of the runner tile to form a sandbelt around the runnertile to stop leakage and. at the same time'prevent formation of finsaround the tile from metal in the matrix of the mold.

Other and further objects of the present invention will in part beobvious and will in part be pointed out hereinafter in thespecificationfollowing by reference to the accompanying drawings,wherein like parts are represented by like characters throughout theseveral figures thereof.

Realizing that the present invention may be embodied in constructionsother than those herein specifically disclosed, it is desired that thepresent, disclosure shall be considered as illustrative and not in thelimiting sense.

Figure 1 is a view of a moldwith the parts thereof separated to showone. form of construction in which the runner tile comprising thepresent invention maybe utilized.

Figure 2 is a front the runner tile. Figure "3 is a side elevation ofthe runner tile. 1Figure'41, is a back View of the runner t1 e. Y YFigures 5 and 6 illustrate the runner tile separated in order to show.the formation of the runner conduit.

Figure 7 is a top View of the runner tile. Figure 8 is a base view ofthe runner tile. Figure 9 is a perspective view of a modified form ofthe invention.

Referring nowto the drawings, the mold elevational view of will only bereferred to in a general way Number 463,160, filed April 21,1921, of

which the present application is a division. Referring therefore to themold in a general way it is preferably formed of sec-' tions, the lowerone comprising a stool 1 provided with a head closing member 2. The bodyof the mold comprises an inverted trough member 4 and the fountain 5 ofthe mold is adapted to set upon .and cooperate with the end of the bodyportion A and with the head closing member 2. Preferably the headclosing member 2 in the present embodiment is provided with awedge-shaped opening into which the runner tile structure is adapted tofit.

The runner tile is formed of sections 6 and 7 which may be easily andcheaply formed by dies in suitable presses. Shallow grooves 8 and 9 areformed in the contiguous faces of thesections so that the desired runnerchannel 10 is formed when the parts are assembled. The plane ofseparation of the parts of the tile preferably is along the verticallongitudinal plane of the ingot, which passes through the majorcross-sectional axis of the runner channel. It will be noted that whenthe sections are assembled the cross-sectional boundary of therunnertile channel is oval in shape with sharp angular corners adjacent theplane of separation of the two parts. This gives greater clearance andallows each half of the tile to be readily separated from the solidifiedrunner or gate which is left in the tile after casting. Thisconstruction permits stripping the tile without breaking so that it maybe used over again until it becomes unfit for use. I

Preferably one section is provided with a groove 11 and the othersection is provided with a tongue 12 which is adapted to fit into thegroove and to position the parts in such manner as to properly form therunner opening 10'. The sides of each section are recessed as at 14, toprovide sand grooves which meet beneath the runner tile. Preferably asmaller sand groove 15 is provided in the back of the tile as well as atthe side. The front of the tile is cut away as at 16 to provide a ventopening for. the mold gases. The tile illustrated in Figures 1 to 8illustrates a tile tapering downward, whereas the tile illustrated inFigure 9 shows a modified form of the tile tapering backward. I

In setting thetile, a thick clay wash may be brushed on the tile in anarrow strip on portions where the tile contacts with the walls of therecess, then after the tile has been set a loose fine dry refractorysand, may be run into the sand grooves and between the tile and itsrespective recesses in which it sets. This fine material will readilypenetrate around the tile while the clay wash will prevent leakage ofthe sand into the mold.

It is evident that these sand groove eonstructionsincrease the clearancespace between the tile and the tile cavity so that the tile is quicklyrelieved of pressure when the ingot is stripped, and facilitates settingthe tile after the mold has been set up because considerable clearancepermits of easily manipulating the parts of the original setup.
